While internet and cellular phones are very attractive to adolescents, they cause a lot of problems because of adolescent's addiction to internet and cellular phones. The purpose of this study is to investigate relations among overuse of internet and cellular phone and academic achievement with middle school students according to their sex and grade. For this purpose, the survey consist of 44-item, self-administered paper-and-pencil questionnaire from 444 two middle schools students located in Busan. Also, their academic achievements were used for statistical data processing. As a result, firstly, middle school students did not tend to be so seriously addicted to the internet and cellular phones. The internet was used more by male students and cellular phones by female students, and the more male and female students used the internet, the higher they tended to use the cellular phones. There was a negative correlation between the tendency of internet use and academic achievement, but there were no significant differences between genders. In terms of the tendency of using cellular phones and academic achievement, there were no correlations among male students, but there was a negative correlation in female counterparts. Secondly, in terms of grade, the 2nd-grade students had a higher tendency to use both of them than the 1st- and 3rd-grade counterparts. The tendency of using the internet and cellular phones, in each grade had significantly static correlation and the higher they tended to use the internet, the lower they had academic achievement the 3rd-grade. On the other hand, the tendency of using cellular phones, only 2nd-grade students had low academic achievement.

This study was attempted to investigate the mediating effect of the tolerance of dating violence in the influence of female college students' perception of dating violence on their sexual self-assertion. The subjects of this study were 161 female students enrolled in universities in the Chungbuk region. As research instrument, Jeong(2013)'s perception of dating violence, Jeong(2016)'s sexual self-assertiveness, and Nam(2003)'s dating violence acceptability were used. For data analysis, frequency, percentage, correlation analysis, hierarchical regression analysis, and Sobel test were performed using SPSS WIN 21.0 program. As a result of the study, first, there was a significant positive correlation between perception of dating violence and violence tolerance(r=.43, p<.001), and a significant negative correlation between violence tolerance and sexual assertiveness(r=-.20, p<.05). Second, the perception of dating violence had a significant positive effect on sexual assertiveness(𝛽=.43, p<.001), and the explanatory power was 19%(F=36.10, p<.001). Third, it was found that the decrease in the effect of female college students' perception of dating violence on sexual assertiveness was significant(Z=2.05, p<.05), violence acceptability showed a mediating effect on the effect of dating violence perception on sexual assertiveness. Based on this study, it is suggested to develop a dating violence prevention program that can lower female college students' acceptability for violence, raise perception of violence, and strengthen sexual assertiveness.

Appearance has become an important means of expressing oneself in modern society, and women often desire to lose weight. Therefore, this study examined the diets of female college students with high weight loss needs and analyzed the effects of their body image, sociocultural attitude, body stress and diet behavior on intake weight loss products. Data were collected from 220 Korean female college students from June to July using an online survey program. The questionnaires included body image scale, Sociocultural Attitude Towards Appearance Questionnaire (SATAQ), Body Attitudes Questionnaire (BAQ) and diet behaviors scale. Data were analyzed by descriptive statistics, the $x^2$-test, Pearson's correlation coefficients, and logistic regression analysis using the SPSS 22.0 program. There were significant differences in body image, SATAQ, obesity stress and diet behavior between groups. All variables were significantly correlated with each other. Factors influencing weight loss products intake by female university students were SATAQ (OR=1.15, CI=1.03-1.29), obesity stress (OR=1.13, CI=1.06-1.20), diet behaviors (OR=1.21, CI=1.10-1.33), and knowledge regarding the side effects of weight loss products (OR=3.86, CI=1.62-9.20). Thus, it is necessary to teach female college students to recognize healthy weight control methods. Moreover, if weight loss products are needed, appropriate information should be provided regarding the ingredients and side effects of the product.

Purpose : This study identified the patterns of smoking of students attending middle schools and high schools, and analyzed its related health risk behaviors. Methods: The data was based on the survey of 1,517 middle students and 911 high students residing in Kyung-Gi district. Results: The current smoking rates of male and female middle students are 5.3%, and 3.1% respectively. The rates of experiences in smoking are 21.4% and 16.0%(male/female). The current smoking rates of male and female high students are 17.9% and 8.5%, whereas the rates of experiences in smoking are 34.2% and 23.3% respectively. On the other hands, 14.1% of middle students and 12.0% of high students were exposed to smoking for at least 2 hours per day. The majority of middle and high school smokers started smoking when they were in middle or high school. And the most popular places to smoke were children's playgrounds, public open area., parks, and so on. Whether having a smoker as a friend or not and students' own perception towards smoking influenced the decisions to smoke for middle and high students. Both middle and high students, regardless of their gender, who have higher rates of drinking experiences and the hours of computer usage were found to have higher rates of smoking experiences. Meanwhile, the sleeping hours is in reverse proportion to the rate of smoking experiences. There was statistically significant difference in smoking experiences related to the degree of obesity only in the female high students: underweight and overweight students showed higher rates of smoking experiences than those falling in the normal weight range. Conclusion: For the effective prevention of adolescence smoking, it is necessary to adopt a comprehensive approach, which classifies the target population according to their age and sex and cover all health risk behaviors.

Purpose: Along with the country's decreasing birth rate, many South Korean women are currently facing the issue of high risk pregnancy. Despite the increasing number of women who prefer to get married at an older age, fewer of them are aware of how to prepare for healthy pregnancy at such age. The following study has been conducted to check the level of awareness and educational demand regarding healthy pregnancy among female university students who are not majoring in medical fields. Methods: Google Forms was used to survey 245 female students attending a university located in the Province of Gyenongi. We asked about their attitudes to and knowledge of pregnancy, their lifestyle, and the demand for pregnancy education. Results: The average age of the participants was 20.4 years. Although the majority of the correspondents answered that they have received education about pregnancy before, many of them displayed a low level of knowledge regarding pregnancy. On contrast, the demand for education about pregnancy and high risk pregnancy was high. Conclusion: For healthier pregnancy and childbirth, more preparation is needed before entering pregnancy. Management programs to be given prior to pregnancy should be developed to promote the knowledge and awareness of healthy pregnancy.

The purpose of this study was to evaluate the dietary behavior, nutrient and food intake status and dietary quality based on nutrient and food group intake and Diet Quality Index-International (DQI-I) according to breakfast eating status in female university students. The survey was conducted using questionnaires and 3-day dietary records for 181 female university students residing in Seoul, Gyunggi, and Gangwon. The subjects were divided into two groups by frequency of breakfast eating: skipping breakfast (frequency of eating breakfast under 4 times/week, n=69) and eating breakfast (frequency of eating breakfast over five times/week, n=112). The skipping-breakfast group was significantly lower in its frequency of having lunch than that of the eating-breakfast group. There was no significant difference of energy intake between the two groups; however, the intake of carbohydrate, fiber, folate, vitamin C, vitamin E, Ca and Fe in the skipping-breakfast group was significantly lower than those in the eating-breakfast group. There was no significant difference in Korean's Dietary Diversity Score (KDDS) between the skipping-breakfast group ($4.65{\pm}0.56$) and eating-breakfast group ($4.73{\pm}0.50$). The average DQI-I of the skippingbreakfast group ($56.96{\pm}9.04$) was significantly lower than that of the eating-breakfast group ($61.32{\pm}7.99$). In conclusion, female university students with a high frequency of skipping breakfast may have a lower diet quality and DQI-I score. Therefore, in support of proper dietary management, it is necessary to promote and support breakfast eating.

The purpose of this study was to estimate the daily intake of vitamin A in Korean female university students. Vitamin A intake was estimated using an inconsecutive 3-day dietary intake survey from 481 young women. Vitamin A intake values were calculated based on the data in USDA database. Average age, height, and weight of the subjects were 20.05 years, 162.13 cm and 54.38 kg, respectively. The subject's average intake of energy was 1645.67 kcal. The mean vitamin A, retinol and ${\beta}$ carotene intakes were $908.35{\pm}863.18$ ug retinol equivalent/day, $199.19{\pm}166.00$ ug/day and $3872.59{\pm}4972.17$ ug/day, respectively. The 21.83% of the subjects consumed less than the Estimated Average Requirement (EAR) for vitamin A. And subjects consumed 141.69% of the Recommended Nutrient Intake (RNI) for vitamin A. Food groups consumed with high vitamin A content in our subjects included vegetables (423.96 ug RE/day), potato and starches (213.64 ug RE/day), cereals (62.60 ug RE/day), eggs (55.17 ug RE/day) and milks (53.45 ug RE/day). The major food sources of vitamin A were sweet potato, carrot, spinach, egg, and cereal, and the top 30 foods provided 89.57% of total vitamin A. Also animal-derived food provided 9.65% of the vitamin A intake from the top 30 foods. In conclusion, judging from RNI, the vitamin A intake of the Korean female university students in this study was generally adequate. The result of our study may be used as a basis for follow-up studies of vitamin A intake like assessment of vitamin A nutritional status or evaluation of carotenoid food sources in Korean young women.

Purpose: The purpose of the study was to examine whether anthropometric estimations can be reliable methods to assess body fat of university students, by identifying the relationship between anthropometric estimates, which have been thought to be not reliable but economic, and Bio-electric impedance analysis (BIA), which has been known to be reliable but expensive. Method: Twenty-one male and 20 female university students were recruited. The in Body 3.0 scale and GIF-891DX were used for BIA. Body fat was estimated with 12 circumferences, 9 skin-fold thicknesses (SFT), and applying 4 equations (Kim's, $Broz{\check{e}}k's$, Siri's and Wilmore's). Their relationships were examined by Pearson Correlation. Result: 11 circumferences and 9 SFT in the male while 5 circumferences and 3 SFT in the female correlated with the body fat on BIA(p<05). The waist circumference had the strongest correlation to the BIA in both males and females. The abdomonial SFT for the male and scapular SFT for the female had the strongest relationship of SFT to BIA. Body fat estimated from more than two different equations significantly correlated with those measured from BIA (p<.05). Conclusion: Anthropometric estimations could be a useful method to get reliable and valid data for body fat of the university students inexpensively.

The purpose of this study was to investigate the lifestyle, food habits, image, perception of beauty and nutrition knowledge between beauty major and non-major college female students. A total of 392 women aged 20s in the survey. SPSS version 21.0 was used for analysis of data. The BMI was high in non-major students (p<0.05), proportion of underweight (p<0.001) and non-drinker (p<0.01) were significantly higher in beauty major students than non-major students. Proportion of total subjects skipped meal by the lack of time. Importance of appearance was significantly higher (p<0.05) in beauty major students. Nutrition knowledge score was significantly higher in beauty major students compared to non-major students (p<0.001).In beauty major students, food intake of meats (p<0.001) and cooked food with oil (p<0.01) were lower white vegetables (p<0.05) and fruits (p<0.01) were higher than non-major students. In conclusion, these results suggest that non-major students need to systematic education program about nutrition and diet.
